ABSTRACT:
A bus circuit comprises a bus interconnection (1) and a plurality of local bus interconnections (10). A plurality of circuit blocks (21a to 21d) are connected to each of the plurality of local bus interconnections (10). A multiplexer (70), a bus driver (60) and a transmitting circuit (80A) are provided corresponding to each of the local bus interconnections (10). Each multiplexer (70) selects one of the outputs from the corresponding plurality of circuit blocks (21a to 21d) and applies the selected one to the bus driver (60). The bus driver (60) drives the bus interconnection (1) according to the output of the multiplexer (70). The local bus interconnections (10) are precharged to a predetermined potential in advance. When any of the plurality of transmitting circuits (80A) is selected, the selected transmitting circuit (80A) either discharges the corresponding local bus interconnection (10) or holds the same at a predetermined potential according to the information on the bus interconnection (1).
